An iPhone bug has been reported which allows users to bypass a locked iPhone and access certain features. This occurs when someone attempts to make an emergency phone call, then quickly presses the hardware lock button. According to the person who seems to have discovered this, the iPhone then gives access to the Phone app, where one can see contacts and make calls. This bug is present on both regular and jailbroken iPhones running iOS 4.1. Apparently, it is not, however, present in the latest beta version of iOS 4.2, so Apple had either already found the bug and corrected it, or corrected the root cause of the issue when fixing other problems in iOS.
